Exactly.
Examples have been few and far between, but I've lived long enough to know of law-enforcement and rescue personnel dying to save some stupid idiot in lousy weather, and even more getting seriously injured trying to do it.
Not to mention the property damage (to both the property of idiots and of other people).
I'm for "freedom" just as strongly as anybody else, but with it comes a sense of responsibility to society (in this case, the taxpayers) as a whole. In times of bad weather, one shouldn't be out and about, lest one be a liability to society (i.e., the taxpayers).
In fact, I see nothing at all wrong with, if it's as bad as it apparently was in Massachusetts last night, ordering the shut-down of sales of alcohol, of places where people congregate (such as theaters and shopping malls), and of commercial deliveries.
It's not like a "snow emergency" lasts forever; one can sit still for a while.
